(3).  Easy installation and removal, small area.

(4).  Simple using and maintenance.

(5).  Safe and reliable operation, no pollution to water, etc

Structure explanation:

1.Submersible electric pump is composed of five parts: water pump,submersible motor,water line,waterproof cable and control switch. Water pump belongs to single suction multistage vertical centrifugal pump.

2.Submersible motor adopts water-filled wet structure,internal chamber was filled with water for cooling the motor and lubricating the bearing.In the operation,due to the changes of temperature,the pressure of the filled water in the internal chamber also changes,it can be automatically regulated by pressure-regulating unit in the lower part of motor.

3.For preventing the sand getting into the motor,the sand-preventing unit including sand slinger and skeleton oil-sealed was installed in the upper part of motor,the whole motor was sealed tightly.

4.There are water injection hole and exhaust hole in the upper part of the motor and discharge hole in the lower part.

5.There are thrust bearing and thrust collar,mainly for sustaining remnant axial force of pump and the empty weight of motor's rotor.

6.The winding of motor stator adopts water-proof electromagnetic wire with good insulating and water-proof functions and rotor adopts squirrel-cage structure.

7.When used in the environment where there are large grittiness or corrosive water,it should adopt the submersible pump made from casting stainless steel or copper alloy.

Q:help with 95 dodge neon sludge and water pump?
If okorder.com/.. Anyway I hope you have better luck, i'd kill someone if they put sugar in my gas tank. Then again i have a locking gas cap. If you have any questions feel free to im me via yahoo messenger.
Q:how to convert a deep well pump to shallow well?
i am assuming you are referring to jet pumps, and not a submersible, you cannot convert a deep jet pump to a shallow. the deep well jet pump has the foot valve down in the well casing. it uses two pipes that go to the foot valve. the deep jet forces water down the well and uses a venturi effect to draw water back up to the tank. the shallow water jet pump only uses one pipe in the well casing. the foot valve is in the pump itself. the venturi is created in the pump itself, and uses a vaccuum type effect to draw water up from the shallow well.
Q:I have a 1991 fleetwood fwd with a streaming coolant leak i the water pump has been replaced was told it is ?
You can't fix it. Wanna' know why? You are here.
Q:water pump in 99 cadillac sts?
Yes because it what allows the engine coolant to flow to keep the car on the right temperature.
Q:How to tell when to replace water pump?
Generally you don't need to replace a radiator unless water is running out of it. As for the water pump, if it was going bad your car would overheat when it was parked and running. Also it really isn't a do it yourself project, that is something you are better off paying a mechanic to do.
Q:how do you fix a washing machine water pump?
its under the machine
Q:How to change water pump on a Honda bf15d short shaft?
Please get the workshop manual. From an imperfect memory it should be in forward gear to expose a link - but I could be confusing it with other brands. This brand has a known issue with the water pump if ever run dry as both the impellor and the housing can be damaged instantly. The pump should always be replaced as a full assembly, housing, seals and impellor, as detritus can easily block water galleries and that requires extensive work to remediate. The thermostat should be checked and replaced at the same time. Worn and damaged impellor material can easily end up through the block, head, thermostat etc. and that must be checked for as well. The lower cylinder can be down on compression caused by local overheating due to this and mud, sand and corrosion reducing water flow. An engine that very much must be flushed and looked after after all use - that includes all the larger models with this brand. They are quite a good engine, but seem very heavy for the output to me - particularly compared to lifting a two stroke on and off....
Q:Acura Legend water pump?
water pump at autozone is about $130.00 to 190.00. to have it installed will be expensive because i think your timing belt in connected to the water pump and that will also have to be replaced. while there in there have them check the belt tensioners and replace if necessary . because this is not the time to go cheap. cause if u don't replace these items one of them could fail and result in permanent engine damage. better safe than sorry . i think it has two tubes. good luck
Q:Is it my water pump? Help?
Year Engine? (Water Pump effecting the Shifting_____:] No!) Could Clogged Valve Body or you just need to change the Fluid Filter. Trickling Sound OK, Never Heard that one. {Hard to say----is the Fan directly connected to the Water Pump?} With the engine off does the Fan move if you Push Pull it up down? Yes Bad Pump Bearing. Do you see a Coolant leak under the center of the engine behind the Radiator? (Leak from weep hole).
Q:Well water pump trouble...?
If the captive air tank has failed you should still get some water flow. if you are not getting any flow and the pump is spinning then the pump may need to be replaced. There is also a pressure switch that may have failed but if that were the case you would have got flow unless the pump burned up. so, bottom line is this. 1) turn power off. let a tiny bit of air out of the Schroeder valve on the captive air tank. if water comes out, the tank is bad. make sure to fill the tank up to about 40psi. 2)turn power off. remove the cover of the pressure switch and clean with compressed air. move the switch back and forth. sand the contacts with emory cloth. 3) if the tank was good turn the power back on and make sure all the valves are open (even the ones you havent touched) if you are still not getting water you should probably call a plumber. most likely at this point you have a bad switch or tank and it has caused your pump to burn up. good luck
